[0029] As Figures 1 - 7 shown, the embodiment of the present invention provides a highly reliable unlocking and separating device, including:

[0030] A mounting base 10, an unlocking device 11, and a fastening base 4. The mounting base 10 includes a bottom plate, on which a mounting groove is provided. The bottom plate is fixedly connected to the equipment mounting frame 12 for fixing the mounting base 10 on the equipment mounting frame 12. The unlocking device 11 is cylindrical in shape, and a screw hole is provided from the center of the surface to the inside. The unlocking device 11 is fixed in the mounting groove. The fastening base 4 is cylindrical in shape, with a hollow cavity inside, a spiral ring provided on the outer wall, and a mounting hole provided at the bottom.

[0031] A separating screw 5, a screw bracket 6, and a spring 7. The screw bracket 6 is funnel-shaped and sleeved outside the separating screw 5. The separating screw 5 and the screw bracket 6 are located in the hollow cavity of the fastening base 4. The head of the separating screw 5 passes through the mounting hole at the bottom of the fastening base 4 and extends into the screw hole on the surface of the unlocking device 11, and is screwed with the unlocking device 11 to fix the fastening base 4 on the unlocking device 11. A limiting edge extends outward from the top edge of the screw bracket 6. The spring 7 is sleeved outside the screw bracket 6. When the separating screw 5 is screwed with the screw hole on the surface of the unlocking device 11, the limiting edge compresses the spring 7.

[0032] An upper mounting plate 2, a separating spring 9, and a fastening nut 1. The upper mounting plate 2 includes a cylindrical shell that can be sleeved on the upper part of the fastening base 4. An installation edge is provided on the outer wall of the cylindrical shell. The fastening nut 1 is located inside the cylindrical shell and is screwed and fixed with the spiral ring on the outer wall of the fastening base 4 to fix the upper mounting plate 2 and the fastening base 4. The separating spring 9 is sleeved outside the fastening base 4. When the upper mounting plate 2 and the fastening base 4 are fixed, the bottom surface of the installation edge compresses the separating spring 9. A separating device 14 is fixed on the surface of the installation edge, and specifically, the device 14 can be fixed by installing a self-locking nut.

[0033] Among them, the thread ring in the screw hole on the surface of the unlocking device 11 is connected to the power supply. When the power supply is turned on, the thread ring can expand and release the separating screw 5. The length of the inner hollow cavity of the fastening seat 4 is not less than the length of the separating screw 5. After the unlocking device 11 unlocks and releases the separating screw 5, under the elastic return of the spring 7, the screw bracket 6 drags the separating screw 5 to retract into the inner hollow cavity of the fastening seat 4, and the spring 7 is used to push the separating screw 5 into the fastening seat 4 to avoid jamming caused by lateral displacement.

[0034] After the unlocking device 11 of the embodiment of the present invention unlocks the separating screw 5, the separating screw 5 is vertically moved and contracted into the hollow cavity of the fastening seat 4 through the small spring 7 to complete the unlocking, as Figure 3 shown; at this time, the separating spring 9 acts to push out the upper mounting plate 2, and the device 14 generates a flipping motion under the action of the top pin 13 to complete the separation.

[0035] In a specific embodiment, the outer wall of the fastening seat 4 is provided with a mounting platform. When the fastening nut 1 is screwed onto the outer wall of the fastening seat 4, the bottom of the cylindrical shell of the upper mounting plate 2 is pressed and fixed on the mounting platform. A limiting boss is circumferentially arranged on the outer wall of the unlocking device 11, and a limiting groove for limiting the limiting boss is circumferentially opened on the inner wall of the mounting groove. The groove wall of the limiting groove is fixedly connected to the limiting boss by screws. An embedding groove is opened on the surface of the mounting groove of the mounting seat 10, and the bottom of the separating spring 9 is embedded in the embedding groove for fixation.

[0036] In a specific embodiment, the contact between the bottom of the screw bracket 6 and the mounting hole at the bottom of the fastening seat 4 is a spherical surface fit. When the fastening seat 4 deflects slightly, the contact surface between the fastening seat 4 and the screw bracket 6 slides around the center of the sphere. At this time, the separating screw 5 can still ensure to be perpendicular to the unlocking device 11, which is convenient for eliminating the jamming caused by the axis misalignment during the separation process, as Figure 4 and Figure 5 shown.

[0037] In a specific embodiment, the contact between the mounting hole at the bottom of the fastening seat 4 and the surface of the unlocking device 11 is a conical surface fit to offset the structural displacement caused by the radial force.

[0038] In a specific embodiment, a limiting cover 3 is further included. The limiting cover 3 is threadedly connected to the top of the fastening seat 4 and is used to limit the separating screw 5 when the separating screw 5 retracts into the hollow cavity of the fastening seat 4.

[0039] In a specific embodiment, a gasket 8 is further included. The gasket 8 is sleeved on the separating screw 5. A limiting platform is arranged at the inner bottom of the screw bracket 6, and the surface of the limiting platform is a plane adapted to the surface of the gasket 8. When the separating screw 5 is screwed into the screw hole on the surface of the unlocking device 11, the separating screw 5 presses and fixes the screw bracket 6 through the gasket 8.

[0040] When the separating device of the embodiment of the present application is installed, first fasten the mounting seat 10 to the product mounting frame 12 with screws, and fix the unlocking device 11 to the mounting seat 10 with screws; pass the separating screw 5 through the screw top bracket, press the spring 7, and pass through the bottom mounting hole of the fastening seat 4. At this time, the spring 7 is in a compressed state. After completion, screw the limit cover 3 into the top of the fastening seat 4; press the separating spring 9 into the groove on the surface of the mounting groove, press the upper mounting plate 2 against the separating spring 9, press it onto the mounting platform of the fastening seat 4, and use the fastening nut 1 to fasten the upper mounting plate 2 to the fastening seat 4. At this time, the installation of the separating device is completed, as Figure 2 shown. Place the device 14 into the mounting frame 12 and fix the device 14 to the upper mounting plate 2 with screws to complete the product installation, as Figure 6 shown.

[0041] During separation, the unlocking device 11 releases the fastening effect on the separating screw 5 through the split nut. The separating screw 5 and the screw bracket 6 move vertically upward under the restoring force of the spring 7 and retract into the internal hollow cavity of the fastening seat 4 and stop when they reach the limit cover 3. At this time, the upper mounting plate 2 loses restraint, and under the rebounding action of the separating spring 9, the upper mounting plate 2 is pushed upward, and the device 14 rotates around the top pin 13 to complete the separation of the device 14, as Figure 7 shown.

[0042] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
